Ultra isolation transformer is a 3 phase transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source which can be a 1 phase or 3 phase, usually for safety. These types of three phase step down or step up Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected together. They are also called 3 phase step down transformer in the industry.

Suitably designed 3 phase step up transformer or step down transformers block interference caused by ground loops. 3 phase transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.

The commonly used models for 3 phase step down transformer are as under :
480 V AC TO 240 V AC 3 Phase Step Down Transformer , Mostly Used In Usa / Latin America For Their Machines.
440 V AC TO 220 V AC 3 Phase Step Down Transformer, Mostly Used To Run Usa Or Japanese Machines.
415 V AC TO 200 V AC 3 Phase Step Down Transformer, Commonly Used Model In India To Run Various Machines.

The commonly used models for 3 phase step up transformer are as under :
240 V AC TO 480 V AC 3 Phase Step Up Transformer. .
220 V AC TO 440 V AC 3 Phase Step Up Transformer. .

Purevolt is having a team of expert which works hard and it the best of their ability to satisfy the requirements of customer.

We keep checking our 3 phase transformers on different quality and technical parameters to find our scope of improvements in our transformers. Our 3 phase step down transformers are widely accepted in market for their reliability and performance .

Simply put, 3 phase step down transformers are used to step down the voltage from one level to desired level, ie. 415 to 240 V , similarly step up transformers are used to boost the voltage from one level to another level ie. 240 to 415 V. these transformers can be designed in various configurations such as delta/star, star/star, star/delta etc. most of the times these transformers are used with imported machineries from western countries such as USA or from Asian countries such as Japan etc. some of the popular models are as under.

• 5 KVA step down transformer
• 10 KVA step down transformer
• 15 KVA step up transformer
• 20 KVA step up transformer
• 25 KVA 3 phase transformer
• 30 KVA 3 phase transformer
• 40 KVA 3 phase isolation transformer
• 50 KVA 3 phase transformer
• Up to 500 KVA.

Three phase step down transformer or single phase dry-type low voltage, LV type 3 phase isolation transformers are manufactured as step up or step down isolation transformers or to adjust the voltage level in the LV distribution grid.

The 3 phase isolation transformers can be supplied either as Open Type 3 phase transformer or Enclosed Type isolation transformer. Enclosed transformers are tailor made to suite harsh / robust conditions. Indoor units (IP21 or 42) are made of Mild steel powder coated to industrial colour. Outdoor type 3 phase step down transformer are made with an Ingress protection rating of IP56 with powder coated enclosures. Purevolt has over 25 years of experience in 3 phase transformer design and manufacturer and we have been exporting these 3 Phase isolation Transformer to lot of countries. These Three Phase step up Transformer are used with Online Ups, Sine Wave Ups , Machineries and equipment’s.
